‘Pretty Little Liars’ hits its 100th episode on June 8, and what better way to celebrate than by bringing back Caleb? The ‘Ravenswood’ expat finally returns to Rosewood! Will he get back with Hanna? Click for our EXCLUSIVE interview with Tyler Blackburn!

Tyler Blackburnmakes his much awaited return back to Pretty Little Liars, but he’s isn’t in the best state of mind — he did see ghosts, after all. Viewers can expect to see “destructive behaviors” in Caleb Rivers’ (Tyler) future, but on the bright side, we got to the bottom of that new hair!

“He’s just openly questioning life as a whole,” Tyler tells HollywoodLife.com EXCLUSIVELY. “I think that he doesn’t trust the world anymore and when that happens, you really start going down a dark path.”

Understandably, Caleb witnessed downright madness in Ravenswood, and he has a tough time opening up to his friends back in liars’ land. “He’s a little reluctant because it sounds crazy, people won’t really get it,” he explains. “He shuts off and I think that’s actually part of the reason why he isolates himself so much — he feels like he’s crazy and he’s in it alone.”

“Toby (Keegan Allen) kinda steps in [and] even Spencer (Troian Bellisario),” Tyler reveals. “They start to see what he’s dealing with and its not pretty so he has a little bit of a support system but it also pushes them away a lot.”

Of course, Spencer dealt with her own problems, turning to drugs in Season 4, so she’s the perfect cushion for Caleb. “She’s the one who’s dealt with her own demons and her own self medication, and Toby’s just sort of a pretty level-headed guy, pretty calm…plus, Caleb and Toby have a little bit of a bromance.”

Caleb Is Back: Reuniting With Hanna?

Hanna (Ashley Benson) must be so excited that Caleb is finally back in Rosewood!

We had to ask Tyler if Haleb would be back on, and he did an A-okay job at teasing us. “We definitely interact together, so I think that will be pleasing to the viewers,” Tyler admitted, “but I’m not going to say whether or not they are making out again.”

In all seriousness, Tyler does reveal that Hanna is a great support system for him, in addition to Toby and Spencer, and she’ll probably have to pave the way for Caleb when it comes to catching him up on Alison. (Remember, when Tyler left, she was still “dead.”)

“He really only knows [Ali] through what the girls told him so he really doesn’t like her,” Tyler admits.

What’s Up With The Hair?

I know you’re all dying to know what prompted the new ‘do. Well, turns out, it was Tyler’s choice.

“It was my decision…I just needed a change in real life and thought it was good for the character, as well,” Caleb tells HollywoodLife.com. “I love it. I really like having my neck exposed. Sometimes I feel like it makes me look like a 15-year-old boy, but other times I feel like I look like more of a man with it. I don’t know. I like it.”
